  • vehicle door handles are equipped with devices for detecting a user's presence.
  • the detection of a user's presence combined with the recognition of a “hands-free” remote access control badge worn by the user, enables the openable body sections of the vehicle to be locked and unlocked remotely.
  • the user wearing the corresponding electronic badge identified by the vehicle wishes to unlock the vehicle, he approaches or touches the vehicle door handle and the openable body sections of the vehicle are then automatically unlocked.
  • the unlocking area the door (or alternatively all the openable body sections) is/are unlocked without any further action by the user.
  • These presence detection devices usually comprise two capacitive sensors, in the form of two electrodes connected electrically to a printed circuit and integrated into the door handle, each in a precise locking or unlocking area.
  • one electrode is dedicated to each area; that is to say, one electrode is dedicated to the detection of the user's approach and/or the contact of his hand in the locking area, and one electrode is dedicated to the user's approach and/or the contact of his hand in the unlocking area.
  • the presence detection device further comprises a radio frequency antenna, usually of the LF (English abbreviation for “Low Frequency”) type.
  • the detection device is connected to the computer of the vehicle or ECU (English abbreviation for “Electronic Control Unit”), and sends it a presence detection signal.
  • the vehicle's computer has previously identified the user as being authorized to access the vehicle; alternatively, it proceeds to perform this identification after receiving this presence detection signal. For this purpose, it sends an identification request via the radio frequency antenna to the badge (or the remote control) worn by the user.
  • This badge responds by sending its identification code by RF (radio frequency) radiation to the vehicle computer.
  • the computer If the computer recognizes the identification code as the code that authorizes access to the vehicle, it triggers the locking/unlocking of the door (or of all the openable body sections). However, if the computer has not received an identification code, or if the received identification is erroneous, the locking or unlocking does not take place.

By measuring the actual frequency of said oscillating circuit, the measurement means M 2 deduce from this the inductance L of the coil 20 .
  • the comparison means M 3 compare the inductance L measured in this way with a threshold inductance value L s representative of the user's pressure on the handle 10 . If the measured inductance is below the threshold inductance value, that is to say L ⁇ Ls, then the user is pressing on the handle 10 , and his intention of locking the vehicle is validated.
  • an equivalent resistance of the oscillating circuit may be measured and compared with a threshold value of equivalent resistance. In this case, if the measured value of the equivalent resistance is greater than the threshold value of equivalent resistance, then the user is pressing on the handle 10 , and his intention of locking the vehicle is validated.
  • the detection device D′ can be used to detect the intention to lock the vehicle, in a reliable manner and without the risk of false positives. This is because the inductive sensor, unlike the prior art capacitive sensor, is not sensitive to external disturbances.
  • the compressible prestressed element, the first part of the casing (which is elastically deformable), and the elastically deformable part of the handle enable the movement of the non-magnetic metal target relative to the coil to be extended without adversely affecting the aesthetic appearance or the ease of use of the handle.
  • the detection device D′ of the invention is designed to measure movements of the target which are very small (20 ⁇ m to 100 ⁇ m), but which are representative of the user's pressure on the locking area for locking his vehicle.
